Hello , is everything alright ? Can I help ?   I have a Promissory Note , but it's not called that . It's a Bill of Exchange .   Similar to a Promissory Note , yes . I can deal with that for you right here . The difference between a Promissory Note and a Bill of Exchange is that this product is transferable and can bind one party to pay a third party that was not involved in its creation .   So , even if someone wasn't directly involved , they can become involved ? Like the bank you cash it in ?   That's right . We didn't issue it to you , but technically we are buying it from you . So , we become involved .   I see . Sorry about this , I'm new in this job and I've never even seen one of these before ! My boss just told me to come here and sort it out .   As long as you have all of the documentation we require you have nothing to worry about .
